A method of implanting a device to maintain a plication within a hollow
organ. The method uses an elongated member having an end effector at its
distal end. The end effector has an outer cylinder having at least one
opening, and an inner cylinder having at least one opening. The inner
cylinder is at least partially disposed within the outer cylinder and the
cylinders are rotatable with respect to each other. The end effector is
detachable from the elongated member such that it can remain within the
body cavity. The method involves the step of inserting the end effector
within the organ of a patient such that it is in contact with tissue. The
method also involves the step of applying vacuum through the elongated
member so as to dispose tissue within the inner cylinder. The method also
involves the step of creating a plication by rotating the cylinders with
respect to each other. The method also involves the step of detaching the
end effector from the elongated member.
